Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when the inner is superimposed on the outer as in Patent Document 1, there is a problem that pet hair easily enters the space (gap) between the outer and the inner and is easily sandwiched.

[0005] The present invention has been made in view of the above conventional problems, and an object thereof is to provide a disposable absorbent article that can make it difficult for pet hair to be sandwiched between the article and the outer.

Means for Solving the Problems

[0006] The main invention for achieving the above objective is a disposable absorbent article used as an outer garment for pets, comprising an absorbent core, a skin-side sheet covering the absorbent core from the skin side, and a non-skin-side sheet covering the absorbent core from the non-skin side, having a front-to-back direction and a left-to-right direction, having wing portions that protrude outward in either the front-to-back direction or the left-to-right direction when one of the directions is designated as a predetermined direction, and the wing portions are provided with joining portions that can be joined to the outer garment when the wing portions are folded back to the non-skin side.

[0007] Other features of the present invention will be made clearer by description in this specification and the accompanying drawings. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a disposable absorbent article that makes it less likely for pet hair to get trapped between the outer garment and the absorbent article. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0010] From the descriptions in this specification and the accompanying drawings, at least the following matters become clear.

[0011] (Aspect 1) A disposable absorbent article used for an outer for a pet, having a front-back direction and a left-right direction, an absorbent core, a skin-side sheet covering the absorbent core from the skin side, and a non-skin-side sheet covering the absorbent core from the non-skin side. When either the front-back direction or the left-right direction is taken as a predetermined direction, it has a wing portion protruding toward the outside in the predetermined direction, and the wing portion is provided with a joining portion that can be joined to the outer in a state where the wing portion is folded back to the non-skin side. A disposable absorbent article characterized by the above.

[0012] According to such a disposable absorbent article, by folding the wing portion and joining it to the outer, it becomes difficult for the pet's hair to enter between the outer and the disposable absorbent article. Therefore, it is possible to suppress the pet's hair from being sandwiched between the outer and the disposable absorbent article.

[0013] (Aspect 2) For such a disposable absorbent article, in a plan view in a state where the wing portion is not folded back, it is desirable that the joining portion is provided at a position that does not overlap with the absorbent core.

[0014] According to such a disposable absorbent article, since the absorbent core and the joining portion do not overlap, the flexibility of the absorbent core can be prevented from decreasing, and the fit can be improved. In addition, since there is a joining portion on the wing portion, it becomes easier to replace or reattach the disposable absorbent article.

[0015] (Aspect 3) Such a disposable absorbent article, it is desirable that the joint portion is provided on the non-skin side of the wing portion.

[0016] According to such a disposable absorbent article, by folding the wing portion back to the non-skin side and joining the joint portion to the outer side, it becomes difficult for the hair of the pet to be caught.

[0017] (Aspect 4) Such a disposable absorbent article, when a direction different from the predetermined direction in the front-back direction or the left-right direction is defined as the crossing direction, it is desirable that the starting point of the protrusion of the wing portion is provided at a position away from the end of the disposable absorbent article in the crossing direction.

[0018] According to such a disposable absorbent article, the length of folding the wing portion becomes shorter, so it becomes easier to fold.

[0019] (Aspect 5) Such a disposable absorbent article, when a direction different from the predetermined direction in the front-back direction or the left-right direction is defined as the crossing direction, it is desirable that in the crossing direction, the joint portion straddles the central position of the disposable absorbent article.

[0020] According to such a disposable absorbent article, having a joint portion at the central position in the crossing direction of the disposable absorbent article (the direction crossing the protruding direction of the wing portion) makes it easier to be stable and less likely to shift when joined to the outer side.

[0021] (Aspect 6) Such a disposable absorbent article, when a direction different from the predetermined direction in the front-back direction or the left-right direction is defined as the crossing direction, the longitudinal direction of the joint portion may be along the crossing direction.

[0022] According to such a disposable absorbent article, it is possible to make the wing portion protruding in the predetermined direction less likely to shift in the crossing direction. Also, the strength at the time of peeling can be increased (the peak can be made larger).

[0023] (Aspect 7) In such a disposable absorbent article, the longitudinal direction of the joint may be aligned with the predetermined direction.

[0024] With such disposable absorbent articles, the joints are continuous in a predetermined direction, making it less likely for adhesive residue to remain.

[0025] (Pattern 8) In such a disposable absorbent article, when a direction other than the predetermined direction among the front-to-back direction or the left-to-right direction is designated as the intersecting direction, the length of the intersecting direction at the starting position of the protrusion of the wing portion may be greater than the length of the intersecting direction at the tip of the wing portion.

[0026] With such disposable absorbent items, the narrow tip makes them easier to insert into an outer container.

[0027] (Aspect 9) In such a disposable absorbent article, when a direction other than the predetermined direction among the front-to-back direction or the left-to-right direction is designated as the intersecting direction, the length of the intersecting direction at the starting position of the protrusion of the wing portion may be smaller than the length of the intersecting direction at the tip of the wing portion.

[0028] With these types of disposable absorbent items, the narrow folded portion makes them easy to bend. Also, the folded position is easy to identify.

[0029] (Aspect 10) In such a disposable absorbent article, it is desirable that the wing portions be provided in pairs on both sides in the predetermined direction.

[0030] Such disposable absorbent articles can be attached to the outer layer on both sides in a predetermined direction. This provides greater stability compared to cases where only one side is attached, and also reduces the likelihood of slippage.

[0031] (Aspect 11) Such disposable absorbent articles are preferably equipped with an expandable member.

[0032] Such disposable absorbent articles can help prevent leakage of urine and other fluids.

[0033] (Aspect 12) In such a disposable absorbent article, the wing portions are provided in pairs on both sides in the predetermined direction, and it is desirable that the direction of expansion and contraction of the expandable member is the predetermined direction.

[0034] Such disposable absorbent articles allow for the application of elastic force between a pair of wing-like portions.

[0035] (Aspect 13) Such disposable absorbent articles may be used as the outer garment that is worn without straddling the pet's hind legs.

[0036] Such disposable absorbent articles can be applied to belly band-type outerwear and are particularly suitable for males.

[0037] (Aspect 14) Such disposable absorbent article may be used as the outer garment that is worn across the hind legs of the pet.

[0038] Such disposable absorbent items can be applied to open-type outer garments that straddle the hind legs of pets, and are particularly suitable for females.

[0039] (Aspect 15) In such a disposable absorbent article, the predetermined direction is the left-right direction, and in the front-to-back direction, it is desirable that the center of the joint is located further back than the center of the disposable absorbent article.

[0040] Such disposable absorbent items can be secured close to the pet's urinary opening.

[0041] ===First Embodiment=== The following describes a diaper 1 for pets equipped with a disposable absorbent article 20 (hereinafter also referred to as the inner 20) according to the present invention. The term "pet" broadly includes vertebrates and invertebrates, typically including dogs, cats, rabbits, hamsters, and also tiger and lion cubs. In this embodiment, a dog will be used as an example of a pet.

[0042] <<Diaper 1 Composition>> Figure 1 is a plan view of diaper 1 in its unfolded and stretched state, seen from the skin side. Figure 2 is a cross-sectional view of AA in Figure 1. Figure 3 is a perspective view showing the outer 10 and inner 20 of diaper 1 separated, and Figure 4 is a plan view of the inner 20 in its stretched state, seen from the non-skin side. Here, "stretched state" refers to the state in which the product is stretched without wrinkles. In the stretched state, the dimensions of each component constituting the product are equal to or close to the dimensions of the individual component.

[0043] The diaper 1 of this embodiment is a type of diaper that wraps around the body of a pet (a so-called belly band type) and is mainly used for male pets. In the unfolded state of the diaper 1, each direction is defined as shown in the figure. That is, the direction along the longitudinal direction of the diaper 1 is called the "left-right direction". The direction perpendicular to the left-right direction and along the width direction of the diaper 1 is called the "front-back direction". The front-back direction corresponds to the direction connecting the head and buttocks of the pet wearing the diaper, with the head side being called the "front side" and the buttocks side being called the "back side". The direction perpendicular to the left-right direction and the front-back direction is called the "thickness direction", with the side that comes into contact with the pet's skin being called the "skin side" and the opposite side being the "non-skin side". In this embodiment, the left-right direction corresponds to the "predetermined direction", and the front-back direction corresponds to the "crossing direction".

[0044] The diaper 1 of this embodiment is composed of a reusable outer 10 and a disposable inner 20. The outer 10 and inner 20 each have a front-to-back direction, a left-to-right direction, and a thickness direction.

[0045] <About Outerwear 10> The outer 10 is a component positioned on the outside (non-skin side) of the diaper 1, and in this case, it is a long, strip-shaped component in the left-right direction. Furthermore, as mentioned above, the outer 10 is reusable. The outer 10 in this embodiment comprises an outer body 11, storage material 12, and locking parts 13 and 14.

[0046] The outer casing 11 is, for example, made of fabric and constitutes the main body of the outer casing 10. The length of the outer casing 11 in the left-right direction is longer than the length of the inner casing 20 in the left-right direction and longer than the circumference of the pet's body. The length of the outer casing 11 in the front-to-back direction is approximately the same as the length of the inner casing 20 in the front-to-back direction.

[0047] The storage material 12 is a component for attaching the inner 20 (specifically, for storing the wing portion 24 of the inner 20). The storage material 12 is made of, for example, cloth and is positioned on the skin side of the outer body 11. The front-to-rear ends of the storage material 12 and the outer body 11 are joined (for example, sewn) along the left-to-right direction. In addition, an expandable member 15 is provided along the left-to-right direction at the front-to-rear end of the storage material 12, and the expandable member 15 provides expandability in the left-to-right direction. The left-to-right ends of the storage material 12 are not joined to the outer body 11. The wing portion 24 of the inner 20, which will be described later, can be stored in this gap (between the outer body 11 and the storage material 12).

[0048] The locking parts 13 and 14 are components for securing the outer garment 10 when it is wrapped around the pet's body. One of the locking parts 13 and 14 (for example, locking part 13) is provided with a locking projection (hook) or the like (not shown), and the other (for example, locking part 14) is provided with a component that facilitates engagement of the locking projection. In the unfolded outer garment body 11, the locking part 14 is provided on the non-skin side of one end in the left-right direction, and the locking part 13 is provided on the skin side of the other end in the left-right direction. This allows the locking parts 13 and 14 to be engaged when the outer garment 10 is wrapped around the pet's body.

[0049] <About Inner 20> The inner 20 is a disposable absorbent article and comprises an absorbent body 21, a skin-side sheet 22, a non-skin-side sheet 23, wing portions 24, an adhesive portion 25, a leak-proof wall portion 26, and an expandable member 27.

[0050] The absorbent body 21 has an absorbent core 21A that absorbs and retains liquids such as pet excrement (e.g., urine). The absorbent core 21A is composed of, for example, crushed pulp or a superabsorbent polymer. In this embodiment, the weight ratio of pulp to superabsorbent polymer in the absorbent core 21A is 1:1 to 4:1. The higher the amount of superabsorbent polymer, the more urine it can retain. The absorbent core 21A may also be covered with a liquid-permeable coating material (not shown).

[0051] The skin-side sheet 22 is a liquid-permeable sheet member positioned closer to the skin than the absorbent body 21 (absorbent core 21A), and is formed from, for example, an air-through nonwoven fabric or a spunbond nonwoven fabric.

[0052] The non-skin side sheet 23 is a sheet member positioned on the non-skin side of the absorbent body 21 (absorbent core 21A). Both the skin side sheet 22 and the non-skin side sheet 23 have a larger planar size than the absorbent body 21, and the absorbent body 21 (absorbent core 21A) is held between these sheets by joining the skin side sheet 22 and the non-skin side sheet 23 around the absorbent body 21. In this embodiment, the non-skin side sheet 23 also forms a leak-proof wall portion 26, which will be described later.

[0053] The wing portion 24 is a part that protrudes outward in the left-right direction from the main body portion of the inner 20 (the rectangular portion shown in Figure 1), and the wing portion 24 is provided with a joint portion with the outer 10 (adhesive portion 25, which will be described later). As shown in Figures 3 and 4, a pair of wing portions 24 are provided on both sides of the inner 20 in the left-right direction. This allows the outer 10 to be joined on both sides in the left-right direction, making it more stable than when it is joined on only one side. It also makes it less likely to shift.

[0054] In this embodiment, the wing portion 24 is formed by both the skin-side sheet 22 and the non-skin-side sheet 23 extending in the left-right direction (see cross-section in Figure 2). However, it is not limited to this, and for example, the wing portion 24 may be formed using only one of the skin-side sheet 22 or the non-skin-side sheet 23, or another sheet member may be joined to the skin-side sheet 22 or the non-skin-side sheet 23 to form the wing portion 24.

[0055] Furthermore, as shown in Figures 3 and 4, the wing portion 24 protrudes in the left-right direction from a position away from the front-rear end of the inner 20. In other words, the starting point of the protrusion of the wing portion 24 is located away from the front-rear end of the inner 20. This makes it easier to fold the wing portion 24 because the length to be folded is shortened. Note that the starting point of the protrusion of the wing portion 24 may also be located at the front-rear end of the inner 20 (the wing portion 24 may protrude from the front-rear end of the inner 20).

[0056] Furthermore, in this embodiment, the length of the wing portion 24 in the front-to-back direction at the starting position of protrusion is greater than the length of the wing portion 24 in the front-to-back direction at the tip (left-right end) of the wing portion 24. Because the tip side of the wing portion 24 is narrow in this way, it is easy to insert the wing portion 24 between the outer casing body 11 of the outer 10 and the storage material 12.

[0057] Furthermore, the length of the wing portion 24 in the front-to-back direction at the starting position of its protrusion may be smaller than the length of the wing portion 24 in the front-to-back direction at its tip (the end in the left-to-right direction). In this case, the folded portion of the wing portion 24 is thinner, making it easier to bend. Also, the folded portion is easier to identify.

[0058] The adhesive portion 25 is, for example, an area to which a hot-melt adhesive has been applied, and is adhesive. In this embodiment, the adhesive portion 25 is provided on the wing portion 24, and can be attached (joined) to the outer 10 (more specifically, the non-skin side of the storage material 12 as shown in Figure 2) with the wing portion 24 folded back to the non-skin side. This allows the inner 20 to be fixed to the outer 10. In this embodiment, the adhesive portion 25 corresponds to the "joining portion".

[0059] As shown in Figure 4, etc., the adhesive portion 25 is positioned so as not to overlap with the absorbent core 21A in a plan view when the wing portion 24 is not folded back. By preventing the absorbent core 21A and the adhesive portion 25 from overlapping, the flexibility of the absorbent core 21A is not reduced, and the fit can be improved. In addition, since the adhesive portion 25 is provided only on the wing portion 24, it is easier to replace or reattach the inner 20. However, the adhesive portion 25 may also be positioned so as to overlap with the absorbent core 21A.

[0060] Furthermore, as shown in Figure 4, the adhesive portion 25 is provided on the non-skin side of the wing portion 24. This makes it less likely for pet hair to get caught between the inner 20 and the outer 10 by folding the wing portion 24 back to the non-skin side and joining the adhesive portion 25 to the outer 10.

[0061] Furthermore, the adhesive portion 25 is located approximately in the center of the inner 20 in the front-to-back direction, and straddles the center of the inner 20 in the front-to-back direction. Having the adhesive portion 25 in the center of the inner 20 in the front-to-back direction in this way makes it easier to stabilize and less likely to shift when attached to the outer 10.

[0062] Furthermore, the planar shape of the adhesive portion 25 is approximately rectangular, and its longitudinal direction is aligned with the front-to-back direction. This makes it difficult for the wing portions 24, which protrude in the left-to-right direction, to shift in the front-to-back direction. It also increases the strength (higher peak) during peeling. Note that the shape of the adhesive portion 25 is not limited to a rectangle. For example, it may be an ellipse with its long axis aligned with the front-to-back direction. Also, although the adhesive portion 25 in this embodiment is formed in a single rectangular shape, it is not limited to this, and for example, multiple elongated rectangles in the front-to-back direction may be arranged in the left-to-right direction (for example, in two rows). Furthermore, the longitudinal direction of the adhesive portion 25 may be aligned with the left-to-right direction. In this case, the continuity in the left-to-right direction makes it less likely for adhesive residue to remain.

[0063] As shown in Figures 1 and 3, a pair of leak-proof walls 26 are provided on both sides of the inner 20 in the front-to-back direction, along the left-to-right direction. The leak-proof walls 26 correspond to so-called three-dimensional gathers, and when the diaper 1 is worn, the pair of leak-proof walls 26 stand up on both sides of the absorbent material 21 in the front-to-back direction, towards the wearer's (in this case, pet's) skin, by the expandable members 27 described later. This helps to suppress leakage of excrement.

[0064] In this embodiment, the non-skin-side sheet 23 has a larger planar size in the front-to-back direction than the skin-side sheet 22, and both ends of the non-skin-side sheet 23 in the front-to-back direction are folded back towards the skin side in the thickness direction at both ends of the absorbent body 21 in the front-to-back direction. The laminated sheet members (skin-side sheet 22 and non-skin-side sheet 23) are then appropriately joined together with a hot-melt adhesive or the like to form the leak-proof wall portion 26. The configuration of the leak-proof wall portion 26 (for example, the width in the front-to-back direction and the laminated state of the sheet members) may differ between the front and rear sides.

[0065] The expandable member 27 is, for example, an expandable sheet member or a thread-like expandable member, and is fixed between the laminated sheet members in the pair of leak-proof wall portions 26 in an extended state in the left-right direction. In other words, the expansion and contraction direction of the expandable member 27 is the same direction (left-right direction) as the protruding direction of the pair of wing portions 24. This allows the expansion and contraction force of the expandable member 27 to be applied between the pair of wing portions 24. Furthermore, when the expandable member 27, which is provided extended in the left-right direction, contracts, the leak-proof wall portion 26 can be raised towards the skin side.

[0066] <<Regarding putting on and taking off innerwear 20>> When attaching the inner 20 to the outer 10, first, as shown in Figure 3, the non-skin side of the inner 20 is placed facing the skin side of the outer 10 (in this case, the storage material 12).

[0067] Next, the pair of wing sections 24 are folded back towards the non-skin side and inserted between the outer body 11 of the outer 10 and the storage material 12.

[0068] Then, the adhesive portions 25 of the pair of wing portions 24 are attached to the outer 10 (in this case, the non-skin side of the storage material 12). As a result, the inner 20 is fixed to the outer 10, as shown in Figure 2.

[0069] When removing the inner 20 from the outer 10, such as for replacement of the inner 20, the adhesive parts 25 of the pair of wing sections 24 are removed from the outer 10 (in this case, the non-skin side of the storage material 12). Then, the pair of wing sections 24 are pulled out from the outer 10, separating the inner 20 from the outer 10.

[0070] <<Regarding the application of diaper 1>> Figures 5A and 5B are diagrams illustrating the process of putting diaper 1 on a pet.

[0071] When putting diaper 1 on a pet (in this case, a dog), first, as shown in Figure 5A, position diaper 1 so that the inner 20 (more specifically, the absorbent core 21A of the absorbent material 21) is against the pet's ventral side (i.e., the side where the pet's excretory organs are located). Then, wrap diaper 1 around the pet's body.

[0072] Next, as shown in Figure 5B, the locking portion 13 is placed on top of the locking portion 14 of the outer casing body 11. This causes the locking projection of the locking portion 13 to engage with the locking portion 14, and the diaper 1 is attached to the pet's body.

[0073] As described above, the inner 20 of this embodiment has wing portions 24 that protrude outward in the left-right direction, and the wing portions 24 are provided with adhesive portions 25 that can be attached to the outer 10 with the wing portions 24 folded back to the non-skin side. By folding the wing portions 24 back to the non-skin side and attaching them to the outer 10 in this way, it becomes more difficult for pet hair to get into the gap between the outer 10 and the inner 20, thus preventing pet hair from getting caught.

[0074] In this embodiment, the inner 20 is attached (joined) to the outer 10 by providing an adhesive portion 25 on the wing portion 24, but the method of joining is not limited to this. For example, locking portions (hooks, etc.) may be provided on the opposing surfaces of the wing portion 24 of the outer 10 and the inner 20 to engage with each other. In that case, the locking portion of the inner 20 corresponds to the "joining portion". The same applies to the modified examples and embodiments described later.

[0075] <First variation> Figure 6 shows a first modified example of the inner 20. Note that Figure 6 is a cross-sectional view of the portion corresponding to Figure 2.

[0076] In the previously described embodiment, the adhesive portion 25 was provided on the non-skin side of the wing portion 24, but in this modified example, the adhesive portion 25 is provided on the skin side of the wing portion 24 (Note that in Figure 6, the wing portion 24 is folded back on the non-skin side, so in the drawing, the adhesive portion 25 is located on the non-skin side of the wing portion 24). The shape of the adhesive portion 25 is the same as in the previously described embodiment.

[0077] In this example, the wing portion 24 is folded back to the non-skin side and inserted between the outer casing body 11 of the outer 10 and the storage material 12, and the adhesive portion 25 is attached (joined) to the skin side of the outer casing body 11. Even in this case, by attaching the adhesive portion 25 of the wing portion 24 to the outer 10 (in this case, the skin side of the outer casing body 11) on both sides in the left-right direction, it can be made less likely to shift relative to the outer 10.

[0078] <Second variation> Figure 7 shows a second modified example of the inner 20. Note that Figure 7 is a plan view corresponding to Figure 4.

[0079] In this second modification, a pair of wing portions 24' are provided at both ends of the inner 20 in the front-rear direction. That is, in this second modification, the wing portions 24' protrude outward in the front-rear direction. Therefore, in this second modification, the front-rear direction corresponds to the "predetermined direction," and the left-right direction corresponds to the "intersecting direction." In addition, adhesive portions 25' are provided on the non-skin side of each pair of wing portions 24'. The shape of the wing portions 24' and adhesive portions 25' is the same as that of the wing portions 24 and adhesive portions 25 in the previously described embodiment. Note that the wing portions 24' in the second modification may be constructed, for example, by joining a sheet member other than the skin-side sheet 22 and the non-skin-side sheet 23, or the wing portions 24' may be constructed from the skin-side sheet 22 and the non-skin-side sheet 23, and the leak-proof wall portion 26 may be formed from a different sheet member.

[0080] In the case of the second modified example, the storage material 12 for the outer 10 is unnecessary. That is, after placing the inner 20 on the skin side of the outer 10 (outer body 11), the pair of wing portions 24' are folded back to the non-skin side, and the adhesive portion 25' is attached to the non-skin side of the outer body 11. Even in this case, it is difficult for pet hair to get into the gap between the outer 10 and the inner 20, thus preventing pet hair from getting caught.

[0081] ===Second Embodiment=== In the first embodiment, diaper 1 was a belly band type that was worn around the pet's torso (i.e., not straddling the hind legs). In the second embodiment, a type of diaper (hereinafter referred to as diaper 2) that is worn straddling the hind legs of the pet will be described. Such diaper 2 is mainly used for females, but may also be used for males.

[0082] <<About the composition of diaper 2>> Figure 8 is a plan view of the unfolded and stretched diaper 2, seen from the skin side. Figure 9 is a plan view of the unfolded and stretched outer diaper 100, seen from the skin side. Figure 10 is a plan view of the stretched inner diaper 200, seen from the non-skin side.

[0083] In the second embodiment, each direction is defined as shown in Figure 8, etc. That is, the direction along the longitudinal direction of the diaper 2 is defined as the "longitudinal direction," and the direction perpendicular to the longitudinal direction in a plan view is defined as the "width direction." The longitudinal direction corresponds to the front-to-back direction of the inner 200, and the width direction corresponds to the left-to-right direction of the inner 200. In this embodiment, the width direction (left-to-right direction) corresponds to the "predetermined direction," and the longitudinal direction (front-to-back direction) corresponds to the "intersecting direction."

[0084] Although not shown in the diagram, the direction perpendicular to the longitudinal and width directions is defined as the "thickness direction," the side that comes into contact with the pet's skin is defined as the "skin side," and the opposite side is defined as the "non-skin side."

[0085] Diaper 2 consists of a reusable outer 100 and a disposable inner 200 (equivalent to a disposable absorbent item).

[0086] <About Outerwear 100> As shown in Figure 8, the outer garment 100 has a ventral waist portion 101, a dorsal waist portion 102, and a crotch portion 103 in the longitudinal direction. The ventral waist portion 101 is the part that will be located on the ventral side of the pet when the diaper 2 is worn. The dorsal waist portion 102 is the part that will be located on the dorsal side of the pet when the diaper 2 is worn. The crotch portion 103 is provided between the ventral waist portion 101 and the dorsal waist portion 102. The crotch portion 103 is the part that straddles the space between the pet's hind legs.

[0087] Furthermore, the outer 100 includes an outer body 111, locking parts 113 and 114, and a tail hole 115.

[0088] The outer body 111 is, for example, made of fabric and, as shown in Figure 9, constitutes the main body of the outer 100 (ventral torso section 101, dorsal torso section 102, and crotch section 103). Also, as shown in Figure 8, the inner 200 is attached to the skin-facing surface on the ventral side of the outer body 111.

[0089] A pair of locking portions 113 are provided on the skin-facing surfaces at both ends of the ventral girth portion 101 in the width direction (left-right direction). The locking portion 114 is a portion that can engage with the locking portion 113 and is provided in a substantially rectangular shape extending in the width direction (left-right direction) on the non-skin-facing surface of the dorsal girth portion 102.

[0090] Furthermore, one of the locking portion 113 and the locking portion 114 (for example, the locking portion 113) is provided with a locking projection (hook) or the like (not shown), and the other (for example, the locking portion 114) is provided with a member that facilitates engagement of the locking projection.

[0091] The tail hole 115 is a tail insertion section (in this case, a through hole) for passing the pet's tail through. In the outer body 111, the tail hole 115 is formed at a position corresponding to the pet's tail. Note that the tail insertion section is not limited to an opening (hole), but may also be, for example, a notch through which the tail can pass.

[0092] As shown in Figures 8 and 9, the ventral torso portion 101 of the outer garment 100 is provided with expandable members 116 that can expand in the width direction. This improves the fit around the torso. Here, the expandable members 116 are provided in three rows spaced apart in the longitudinal direction (front-to-back direction), but this is not limited to this. For example, one row may be used. In addition, expandable members 117 that can expand in the longitudinal direction are provided at both ends in the width direction of the crotch area 103. This improves the fit around the legs. Furthermore, an expandable member 118 is provided in the crotch area 103 so as to surround the tail hole 115. This improves the fit around the tail.

[0093] <About Inner 200> The inner 200 comprises an absorbent 201 (absorbent core 201A), a skin-side sheet 202, a non-skin-side sheet 203, a wing portion 204, an adhesive portion 205, a leak-proof wall portion 206, and an expandable member 207. The basic configuration of the inner 200 is the same as that of the inner 20 of the first embodiment.

[0094] The absorber 201 has an absorbent core 201A. In this embodiment, the absorbent core 201A has a substantially rectangular shape that is elongated in the front-to-back direction when viewed from above.

[0095] The skin-side sheet 202 is a liquid-permeable sheet member positioned closer to the skin than the absorbent body 201 (absorbent core 201A).

[0096] The non-skin side sheet 203 is a sheet member positioned on the non-skin side of the absorbent body 21 (absorbent core 21A). The skin side sheet 202 and the non-skin side sheet 203 are larger in shape than the absorbent body 201. The outer edges of the skin side sheet 202 and the non-skin side sheet 203 are joined together, thereby holding the absorbent body 201 (absorbent core 201A) between these sheets.

[0097] The wing portion 204 is a part that protrudes outward in the left-right direction from the main body portion (the rectangular portion shown in Figure 8) of the inner 200. In this embodiment, both the skin-side sheet 202 and the non-skin-side sheet 203 extend in the left-right direction to form the wing portion 204. However, this is not limited to this, and for example, the wing portion 204 may be formed by joining other sheet members. As shown in Figure 10, a pair of wing portions 204 are provided on both sides of the inner 200 in the left-right direction.

[0098] The adhesive portion 205 (corresponding to the joint portion) is provided on the wing portion 204, and the wing portion 204 can be folded back to the non-skin side and attached (joined) to the outer 10 (more specifically, the non-skin side of the outer body 111). This allows the inner 200 to be fixed to the outer 100.

[0099] In Figure 10, C1 is the center position of the inner 200 in the front-to-back direction, and C2 is the center position of the adhesive part 205 in the front-to-back direction. As shown in the figure, it is desirable that the center position C2 of the adhesive part 205 in the front-to-back direction is located further back than the center position C1 of the inner 200 in the front-to-back direction. This allows the outer 100 to be fixed closer to the pet's excretory organs (urinary opening).

[0100] Furthermore, the adhesive portion 205 is provided on the non-skin side of the wing portion 204. This allows the adhesive portion 205 to be attached (bonded) to the non-skin side of the outer 100 (outer body 111) by folding the wing portion 204 back to the non-skin side. In this way, by folding the wing portion 204 back to the non-skin side and bonding it, it is possible to prevent pet hair from getting caught between the outer 100 and the inner 200, similar to the first embodiment. In addition, since a pair of wing portions 204 and adhesive portions 205 are provided at both ends in the left-right direction, they can be bonded to the outer 100 on both sides in the left-right direction, making them less likely to shift.

[0101] The adhesive portion 205 is provided only on the wing portion 204, and is positioned so as not to overlap with the absorbent core 201A in a plan view when the wing portion 204 is not folded back. By preventing the absorbent core 201A and the adhesive portion 205 from overlapping, the flexibility of the absorbent core 201A is not reduced, thereby improving the fit.

[0102] Furthermore, the longitudinal direction of the adhesive portion 205 is aligned with the front-to-back direction. This makes it less likely for the wing portion 204, which protrudes in the left-to-right direction, to shift in the front-to-back direction.

[0103] The leak-proof wall sections 206 are provided in pairs along the front-to-back direction at the left-to-right ends of the inner 200. The leak-proof wall sections 206 are made of sheet members joined to the skin side of the skin-side sheet 202. The leak-proof wall sections 206 correspond to so-called three-dimensional gathers (here, leg-side gathers), and when the diaper 2 is worn, the pair of leak-proof wall sections 206 stand up on both the left-to-right sides of the absorbent body 201 towards the wearer's (here, pet's) skin by the expandable member 207, which will be described later. This helps to suppress leakage of excrement.

[0104] The expandable member 207 is, for example, an expandable sheet member or a thread-like expandable member, and is fixed in a state of being extended in the front-rear direction between the laminated sheet members in the pair of leak-proof wall sections 206. When the expandable member 207 is retracted in the front-rear direction, the leak-proof wall section 206 stands upright.

[0105] <<Regarding the application of diaper 2>> Figures 11A and 11B are diagrams illustrating the process of putting diaper 2 on a pet.

[0106] When putting diaper 2 on a pet, first, as shown in Figure 11A, the pet's tail is passed through the tail hole 115, and the diaper 2 is placed against the pet's body and folded in half lengthwise. In this state, the ventral waist portion 101 of diaper 2 is positioned on the pet's ventral side, and the absorbent material 201 (absorbent core 201A) of inner 200 is also positioned on the pet's ventral side (i.e., the side where the pet's excretory organs are located). By using the tail hole 115 as a reference, the absorbent material 201 can be correctly positioned at the location of the pet's excretory organs. On the other hand, the locking portion 114 of the dorsal waist portion 102 of diaper 2 is positioned on the pet's dorsal side.

[0107] Next, the pair of locking parts 113 provided on the ventral girth section 101 are pulled upward on both sides in the width direction (left-right direction), and the locking projections of the locking parts 113 are hooked onto the locking parts 114 provided on the dorsal girth section 102 to lock (engage) them. This forms the girth opening HB and the pair of leg openings HL as shown in Figure 4B, and the diaper 2 is attached to the pet's body. In addition, three-dimensional gathers (leg side gathers) are formed in the pair of leg openings HL by the leak-proof wall section 206.

[0108] <Modified form of the second embodiment> The outer casing 100 may be provided with storage material, such as the storage material 12 of the first embodiment, to which the wing portion 204 can be inserted (stored). In this case, the adhesive portion 205 may be provided on the skin side of the wing portion 204.

[0109] Furthermore, as described above, when providing storage materials, the pair of wing portions 204 (including the adhesive portion 205) may be configured to protrude in the front-rear direction. In this case, the front-rear direction corresponds to the "predetermined direction," and the left-right direction corresponds to the "intersecting direction."
